Hi
Planted aquariums are not easy. A lot of work is involved. What if you show him the PPS articles and let him decide.
My personal recommendation for beginners is
PPS with water changes. It is the best method eliminating most of the problems people had in the past with other systems.
The table tells you how to make the fertilizer and how much to dose.
No testing required.
